We have a Model Y and joke that it drives like a beta test.
We don't have full self driving, but even autopilot does lots of weird and scary things at times. It's great 99% of the time, but that 1% has its terrifying moments.
The single stick to change gears and stop/start autopilot is also finicky, so you have to really check that the car is doing what you expect. Relying on muscle memory like other cars doesn't cut it.
